javaweb分享功能实现_开发（⼀）基于Wx-java的分
享功能
最近在做服务号开发，简单总结⼀下，便于⾃⼰学习积累和分享给⼤家：
环境介绍：
Spring+ Spring MVC +Mybatis
开发语⾔：
JAVA
公众平台的开发中，只公布了⼀个基于Http协议的接⼝和加解密的算法sdk，在开发的过程中可以⾃⼰根据需求来配置数据，调⽤
相关接⼝，也可以引⽤⽐较成熟的基于java语⾔的sdk。笔者引⽤的是⽬前⽐较流⾏的
weixin-java-tools
可以参考：点击打开链接
项⽬中引⼊了weixin-java-mp 就可直接调⽤相关功能接⼝和完成jssdk认证

weixin-java-mp
3.3.0

(不同模块参考下⽂)
3.3.0
各模块的artifactId：
⼩程序：weixin-java-miniapp
⽀付：weixin-java-pay
开放平台：weixin-java-open
(包括和服务号)：weixin-java-mp
企业号/企业：weixin-java-cp

相关官⽅⽂档
WxMpService提供了以下⼏个⽅法：
public String getJsapiTicket() throwsWxErrorException;public String getJsapiTicket(boolean forceRefresh) throwsWxErrorException;public WxJsapiSignature createJsapiSignature(String url) throws WxErrorException;
分享接⼝：
1.后台准备：有趣的java小程序
建⼀个公⽤控制类： WeXinJsSdkController ，通过ajax 访问完成jssdk认证：
importme.chanjar.weixinmon.bean.WxJsapiSignature;importme.WxErrorException;importme.c
@Controller
@RequestMapping("jssdk")public classWeXinJsSdkController {
@AutowiredprivateWxMpService wxMpService;
@RequestMapping(value= "/config", method =RequestMethod.GET)
@ResponseBodypublicWxJsapiSignature wxJsSdkConfig(HttpServletRequest request, String url) {try { //直接调⽤wxMpServer 接⼝
WxJsapiSignature wxJsapiSignature =ateJsapiSignature(url);returnwxJsapiSignature;
}catch(WxErrorException e) {return null;
}
}
}
packageme.chanjar.weixinmon.bean;importjava.beans.ConstructorProperties;importjava.io.Serializable;public class WxJsapiSignature implementsSerializable {private static final long serialVersionUID = -

}publicString getAppId() {return this.appId;

}public voidsetSignature(String signature) {this.signature =signature;
}public booleanequals(Object o) {if (o == this) {return true;
}else if (!(o instanceofWxJsapiSignature)) {return false;
}else{
WxJsapiSignature other=(WxJsapiSignature)o;if (!other.canEqual(this)) {return false;
}else{
label63: {
Objectthis$appId = AppId();
Object other$AppId();if (this$appId == null) {if (other$appId == null) {breaklabel63;

}
}else if (!this$signature.equals(other$signature)) {return false;
}return true;
}
}
}
}protected booleancanEqual(Object other) {return other instanceofWxJsapiSignature;
}public inthashCode() {int PRIME = true;int result = 1;
Object $appId= AppId();int result = result * 59 + ($appId == null ? 43: $appId.hashCode());

@ConstructorProperties({"appId", "nonceStr", "timestamp", "url", "signature"})public WxJsapiSignature(String appId, String nonceStr, longtimestamp, String url, String signature) {this.appId =Str =nonceStr;this.timestamp

this.signature);
}publicString toString() {return "WxJsapiSignature.WxJsapiSignatureBuilder(appId=" + this.appId + ", nonceStr=" +
}
}
}
2.页⾯初始化js 配置相关接⼝：
/*初始化jssdk 分享功能*/$.get("${basePath}/jssdk/config.do",{url:window.location.href},function(data,status){if(status == "success"){
debug:false, //开启调试模式，调⽤的所有api的返回值会在客户端alert出来，若要查看传⼊的参数，可以在pc端打开，参数信息会通过log 打出，仅在pc端时才会打印。
appId: data.appId, //必填，的唯⼀标识
timestamp: data.timestamp, //必填，⽣成签名的时间戳
nonceStr: Str, //必填，⽣成签名的随机串
signature: data.signature,//必填，签名，见附录1
jsApiList: ['checkJsApi', 'onMenuShareTimeline', 'onMenuShareAppMessage', 'onMenuShareQQ'] //必填，需要使⽤的JS接⼝列表，所有JS接⼝列表见附录2
});
//对于⽤户触发时才调⽤的接⼝，则可以直接调⽤，不需要放在ready函数中。
var shareData ={
title:'${ainsubject}',
desc:'${description}',//link: 'www.baidu', // 分享域名要和当前域名保持⼀致！！
imgUrl: 'fd/tektcrm/EventNoti/images/attendance.png',
success:function(res) {//alert('已分享');
},
cancel:function(res) {//alert('已取消');
},
fail:function(res) {//alert(JSON.stringify(res));
}
};wx.onMenuShareAppMessage(shareData);wx.onMenuShareTimeline(shareData);wx.onMenuShareQQ(shareData);
});
<(function(res){//config信息验证失败会执⾏error函数，如签名过期导致验证失败，具体错误信息可以打开config的debug模式查看，//也可以在返回的res参数中查看，对于SPA可以在这⾥更新签名。//layer.msg(res);
});
}
},"json");
学习在于不断地探索、思考和总结记录，欢迎喜欢的朋友们在下⽅留⾔，与君共同进步！

签名算法
签名⽣成规则如下：参与签名的字段包括noncestr(随机字符串), 有效的jsapi_ticket, timestamp(时间戳), url(当前⽹页的URL，不包含#及其后⾯部分) 。对所有待签名参数按照字段名的ASCII 码从⼩到⼤排序(字典序)后，使⽤URL键值对的格式(即
key1=value1&key2=value2…)拼接成字符串string1。这⾥需要注意的是所有参数名均为⼩写字符。对string1作sha1加密，字段名和字段值都采⽤原始值，不进⾏URL 转义。
即signature=sha1(string1)。 ⽰例：
noncestr=Wm3WZYTPz0wzccnW
jsapi_ticket=sM4AOVdWfPE4DxkXGEs8VMCPGGVi4C3VM0P37wVUCFvkVAy_90u5h9nbSlYy3-Sl-
HhTdfl2fzFy1AOcHKP7qg
timestamp=1414587457
步骤1. 对所有待签名参数按照字段名的ASCII 码从⼩到⼤排序(字典序)后，使⽤URL键值对的格式(即key1=value1&key2=value2…)拼接成字符串string1：
步骤2. 对string1进⾏sha1签名，得到signature：
0f9de62fce790f9a083d5c99e95740ceb90c27ed
注意事项
1.签名⽤的noncestr和timestamp必须与wx.config中的nonceStr和timestamp相同。
